The TLV230x combines sub-micropower operational amplifier and comparator into a single package that
produces excellent micropower signal conditioning with only 1.4 μA of supply current. This combination gives
the designer more board space and reduces part counts in systems that require an operational amplifier and
comparator. The low supply current makes it an ideal choice for battery-powered portable applications where
quiescent current is the primary concern. Reverse battery protection guards the amplifier from an over-current
condition due to improper battery installation. For harsh environments, the inputs can be taken 5 V above the
positive supply rail without damage to the device.
The TLV230x’s low supply current is coupled with extremely low input bias currents enabling them to be used
with mega-ohm resistors making them ideal for portable, long active life, applications. DC accuracy is ensured
with a low typical offset voltage as low as 390 μV, CMRR of 90 dB and minimum open loop gain of 130 V/mV
at 2.7 V.
The maximum recommended supply voltage is as high as 16 V and ensured operation down to 2.5 V, with
electrical characteristics specified at 2.7 V, 5 V, and 15 V. The 2.5-V operation makes it compatible with Li-Ion
battery-powered systems and many micropower microcontrollers available today including TI’s MSP430.
All members are available in PDIP and SOIC with the duals (one op-amp and one comparator) in the small
MSOP package, and the quads (two operational amplifiers and two comparators) in the TSSOP package.
